Application filed August 11,1915. Seri'aI NO.14,4,967.

Be it known that I,4JQHN A. Sworn), a

fullmprovements in Binder-Trips for Harvesters; and I do hereby declare thefollowing. to be a full, clear, and exact description of the. invention, .such as will-.enable others j skilled in the art to .which it appertains to.

This invention relates to newanduseful improvements in. harvesting machines and; isparticularly directed to the-provision of;

.trip means for the binder. mechanismthereof.

Much inconvenience isencountered in the operation of harvesting machinesincluding binders in. that thetripmechanism for said. binders sometimes becomes stuck or eotherwise fails to work, or sometimes an excess of grain isencountered which; clogs: the mechanism. It is therefore the .object; of the present invention torprovide a manually." operated vmeans .for positively actuating the trip mechanism at will by the operator sitting; on the seat of themachine. i It is further an: object totprovidesuch... a device-which maybe readily .attached to; harvesting machines of standard types now-i,

- on the market, and whereinmeans are provided-for the shifting of thelbinder mechanism with relation. to the.body of the ma- .v

chine.

-With the aboveiand-aother objects andad-w vantages in View, the invention resides more, particularly. in the novel combination, for-t. mation and arrangement; ofrparts asmore. fully described hereinafterandpointed out,,. in the appended claims. 1

Reference. is had to theaccompanyingy drawings, wherein similar characters.v of reference ydesignate corresponding parts. throughout. the several. views, in L which Figure 1 is atop plan view of a portion of a harvesting machine of v conventional..- type having associated therewith the improved manually operated means for actuating the tripping mechanism. Fig. 2 is a view showing the "seat pipe of the machine and the portion of the improved device car-' ried thereby in side elevation. Fig. 3 is a front elevational view of the structure shown in Fig. 1. Fig. 4 is a perspective view of the forward end of the binder pipe and the improved mechanism carried thereby. Fig.

i sectipnal vi w n the line 5.,5 of Fig. i 1.-:Fig. 5, is a..-detail.sectional view taken citizen of theUnited States, residing at.Abilene, in the.county= o-f-gDickinson, State of Kansas,. have invented certain new andusethrough, the adjustable .connection between 9@t.1 n 0f. the dev ce; a he link ext nding there o Referring now more particularly to the accompanying drawings, the harvester with which the present manual tripping mechanism is,;associated is of, the generalconvenqn g wtype fou d, n. H aring harve ing =.irljaching-gs andincludesthc main cutter frame 5 which has at-one forward corner a depending bearing 6, in. which is slidably mounted the ,binder; pipe 7 which vis shiftable inoperation of the binder mechanism. EX-

;tending over. the frame 5 is theseat pipe 8 carrying the seat 9,. and this pipeterminates adjacent andahove the forward end of the ,frame 5. ;There is also shown at 10 a portion of the elevator-frame.- Associated with .the binder mechanism of the machine is the ,usual ,automatic atrip mechanism, the only part ofnvhich being shown is the trip shaft 11 jonrna'led. in. suitable bearings- 12 which .are gadapted, totdepend from the binder structure, the shaft carrying at. its forward end anoifyset or crankportion 13. The improvedmeans associated with this structure w hereby thetrip shaft 11 may be rocked to trip the binder, by the operator from the seat on the machinecomprises a squared shaft .14, which has its, ends rounded and .journazled. in-arms.l5 upstanding from the .forward portion of the binder pipe 7, the forward of these arms 15 having a lateral attachingportion 16 slotted to receive the securing "bolt 17 .thereof,.:whereby adjust- .ment. maybe had toaproperly'adjust the bearings withrelation to the'shaft.= .An arm 18upstands fromthe. forwardportion of the sh'aftand pivotally connected to this arm is one..end of a link-19"which has its other end-bent to.,form loop 20. in which is en- .gagedthe crankportion 13: ofthe trip shaft 11, said crank portion normally lying in the outer portion of. the loop so. that it hasfree .lmovement. to permit the normal automatic action of the binder trip:- .For rocking the shaft 14: to thus rock the binder shaft by meanscarried on the frame asleeve 21 having' a square bore is slidable on the shaft inwardly of the arm 18 and the forward end of this sleeve carries an upwardly and forwardly extending arm 22. As stated the binder pipe 7 moves with relation to the frame and to hold the sleeve 21 against such forwardly over the frame.

movement on by said pipe, to prevent distortion of the actuating means carried by the frame a plate 23 is adjustably secured on the end of the frame by a bolt 24 passed through a vertical slot 25, and this plate carries a down-,

wardly and outwardly extending arm 26 which has its free end curved at 27 to seat on the sleeve. This curved end is disposed between the arm 22 and upstanding flange 28 at the other end of the sleeve whereby the sleeve is held againstsliding' in either direction. The means for rocking this arm 22 includes a foot lever 29 which is intermediately pivoted to the pipe 8 forwardly of the seat and carries at its upper end the'foot plate 30. The lower end of this lever is pivoted between thebifurcated ends 31 of a socket member 32 in which is threadedly engaged one end of a link 33 which extends An upstanding arm 34 is secured at the forward end of the seat pipe 8 by providing it with a plug 35 screwed in said end of the pipe and pivoted to the upper end of this arm is an angle lever 36 which lies in a horizontal plane and which has pivotally secured to one of its arms'the forward end of the link 33. A link 37 connects the other arm of the lever to the arm 22 whereby when the foot lever 29 is rocked, said arm 22 will be rocked to rockthe shaft 14 and consequently rock the binder trip shaft 11. The

structure described is held in normal inop erative positionby a spring 38 secured to the last named arm of the angle lever 36 and toa hook 39 carried on the elevator frame 10.

From the foregoing description it is observed that a comparatively simple structure has been provided, which may be readily attached to a conventional type of harvester I to efliciently perform the functions set forth and without interfering in any manner with the normal operation of the trip mechanism or any other part of the machlne.

- justment of the device may be had by ad- 'justing the link 33 in the socket member 32.

While I have illustrated and described a particular embodiment of my invention, .1 have merely done so for the sake of con venience'andI do not wish to be limited to that particular embodiment as it is obvious that numerous changes may be made within the details of construction thereof without in any way departing from the spirit ofthe invention or exceedingthe scope of the inl vention as claimed.

Copies of this patent may be obtained for five cents each, by addressing the While the arms 15 which support the shaft 14c are described as extending upwardly,said arms to meet other conditions of service, may extend horizontally from the pipe 7 with slight changes in the proportions of the various parts.

VVhatI claim is:

'1. In a binder including a frame, a shift able pipe, and a trip shafthaving a crank; means to operate the trip shaft controlled by the operator of the binder and comprising a lever pivoted intermediate its ends to a fixed part of the binder, a pedal on said lever within reach of the operator, a bell crank lever pivoted at its angle to a fixed binder part, a rod connecting the first lever to one arm of the bell. crank lever, bearings fixed on the pipe, and movable therewith, a polygonal rock shaft having journal ends mounted in said bearings, a rock arm fixed on said shaft, a link having one end pivoted. to said rock arm and provided at its other end with a slot receiving said crank. a sleeve having a polygonal bore slidably fitting said rock shaft, a second rock arm carried by said sleeve, a link connecting the second rock arm and the remaining arm of the bell crank lever, said sleeve having a collar at one end, an arm fixed to said frame and having a curved plate at its free end fitting the sleeve between the collar and the second rock arm, and a spring having one end connected to the bell crank lever and its other end connected to a fixed binder part to hold the parts normallv in inoperative position.
